Proteins
The second main chemical constituent of the plasma membrane is protein. Integral proteins are encapsulated in the plasma membrane and might stretch a part or all of the membrane and act as pumps or channels that help in the movement of particles inside and outside of the cell. Peripheral proteins are present on the internal areas or exterior of the plasma membrane, attached to either phospholipid molecules or to integral proteins. Integral and peripheral proteins both acts as enzymes, as constructural bonds for cytoskeleton fires, or as a component of recognition sites of the cell.
Receptors are the recognized sites on the membrane that are sites for attachments for materials that collaborate with the cell, and each receptor is formed to attach to a particular material. The attachment of a particular material to its receptor on the plasma membrane accelerates activities inside the cell, like stimulating enzymes engaged in metabolic pathways. These metabolic pathways are important for giving energy to the cell, preparing substances for the cell or toxins for discarding or breakdown of the cell's waste. In addition, neurotransmitters and extracellular hormones attach to receptors of the plasma membrane that transfer a signal into the cells to molecules inside the cell. Viruses use some recognition sites as attachment points. Howbeit they are largely specified, disease-causing organisms like the virus may emerge to misuse the recognition sites to enter inside the cell by imitating the particular substance that is meant to be bound with the receptor. This particularity aids in the explanation of why HIV (Human Immunodeficiency Virus) or the hepatitis virus conquers only particular cells.
Deer-Resistant Shrubs That Will Protect Your Garden From Grazing
Shrubs are a beautiful addition to any yard—they fill in gaps between your plantings, offer multiple seasons of interest, and many varieties yield beautiful blooms for added color. While this all sounds great, you may be encountering one issue when it comes to your shrubs: deer. Luckily, peaceful coexistence is possible. It just takes the right type of deer-resistant shrubs.
National birds | World of Birds | The anti-poaching squad has been conducting raids and the seizure of 12 peacocks, listed as schedule-1 protected species.
It was just over a month since forest officials seized 12 peacocks from the old city residence of a pet shop owner and slapped cases against him. Sleuths of the anti- poaching squad could not arrest him then, for violation of the Wildlife Act, 1972, by breeding the national bird in captivity. Any action against him now appears quite unlikely.
The assistant conservator of forests (surveillance cell) Kondal Rao has been sent on deputation to Hyderabad Metropolitan Development Authority, whereas the post of forest range officer (anti-poaching) has been lying vacant for over four months. Deputy forest range officer SK Baba Khadir Vali, who led the raid, has been shifted to forest utilisation office. That leaves only two wildlife associates (temporary posts) to enforce the Wildlife Act.
According to sources in the department, the pet shop owner, SA Sohail, who runs Fur and Feathers in Banjara Hills, also had business partnership with Nehru Zoological Park for supply of exotic birds.
Sohail has, according to officials, supplied exotic birds to the zoo and is learnt to have been breeding peacocks, including two pure white peacocks, in the cellar of his house in Mochi Colony, Kalapathar. It is also learnt that those who raided Sohail’s house had come under fire from their bosses and explanation was sought from some in the form of showcause notice. However, the principal chief conservator of forests (wildlife) AV Joseph was unavailable for comments despite repeated attempts.
Officials, based on a tip off, raided Sohail’s residence on May 11 and could not arrest him since he was in Mumbai then. But cases were registered against him under section 9 and 39 of the Wildlife Act, which would get him imprisonment up to 7 years.
“Sohail has come back and is very much in Hyderabad. It is just that no one in the department is showing any interest in following up the case and arrest the offender,” pointed out an official on condition of anonymity.
The anti-poaching squad has been conducting raids and the seizure of 12 peacocks, listed as schedule-1 protected species, was certainly one of their biggest catch till date. Hunting, petting and breeding of any wildlife species listed in schedule I and II can attract imprisonment of three to seven years.
